The invention provides a water-based two-component single-coat crack paint, which specifically includes component A: 1-10 parts of deionized water, 45-60 parts of water-based hydroxy acrylic emulsion, 0.2-0.4 parts of dispersant, and 0.1 part of defoamer ~0.2 part, wetting agent 0.1-0.2 part, thickener 0.4-0.6 part, anti-settling agent 0.1-0.2, precipitated barium sulfate 20-31 part, calcium carbonate 4-9 part, pigment 3-20 part, crack aid 1-6 parts of wetting agent, 0.1-0.2 part of substrate wetting agent, 0.1-0.2 part of anti-corrosion agent, 0.1-0.2 part of anti-mildew fungicide; Part B: DB82547 isocyanate curing agent; Part A and Part B according to 6 ~9:1 mix. The paint has properties similar to 0VOC, and at the same time, the paint has good construction ability, and has good cracking effect on different primers and substrates. The paint film has good physical and chemical properties and excellent salt spray resistance. |
